Half a hologram - all the information

Is there really all the information of a recorded motif in every fragment of a hologram? In this example, a broken photo plate is supposed to show us whether we can reconstruct the white-light hologram of a helicopter recorded in it. The photo plate was rotated again in 1-degree steps to the reference wave (focused beam of a light-emitting diode flashlight) for each individual photo, so that several views of the three-dimensional object can be observed from the recorded wave field (light amplitude and phase) of the

While the intensity (amplitude) of the light is recorded in black and white photography, color photography also uses its frequency. In this way, two-dimensional images of our four-dimensional world are generated, which, with the appropriate image composition, can also create a perspective-spatial, three-dimensional impression and, through the choice and representation of a suitable motif, can also create the impression of a temporal component.
